Physicist Stephen Volz had been working with colleagues at the U.S.’s National Oceanic and Atmospheric Administration for nearly 10 years to produce a new generation of geostationary satellites — instruments that would provide critical observations about atmospheric conditions, climate patterns and weather. But when Donald Trump returned to office in January 2025, this long-term project was thrown into disarray. “This administration canceled three of the five instruments on that program,” Volz, the assistant administrator for NOAA’s National Environmental Satellite, Data, and Information Service, who has been on administrative leave since July 2025, told Mongabay. The cancellations applied to instruments that measured air pollutants, tracked lightning to forecast hurricanes and tornadoes, and monitored ocean color to detect events such as algal blooms, sargassum seaweed surges and salinity changes, according to Volz. “They said, ‘those are all wasted money, they’re climate alarmist, I don’t need air quality, I don’t need ocean color,’” Volz said about the administration’s decision. The axing of this project is just one example of what experts describe as a broad, long-term effort by the Trump administration to weaken NOAA. The long-standing scientific and regulatory agency within the U.S. Department of Commerce has historically been responsible for everything from forecasting the weather and monitoring the climate to managing fisheries and protecting marine mammals. The White House did not respond to Mongabay’s request for comment. NOAA’s GOES-19 satellite, which tracks hurricanes and tropical storms in the Atlantic Ocean basin, as well as monitor severe weather, atmospheric rivers, wildfires, volcanic eruptions…This article was originally published on Mongabay

A version of this story was originally published by the Pulitzer Center, which supported Elizabeth Claire Alberts as an Ocean Reporting Network fellow. We didn’t set out to investigate China’s deep-sea mining fleet, but as our research into the burgeoning industry developed over our yearlong partnership, it became clear that an investigation into the fleet’s alleged military dual use was emerging as an important, untold story. Shortly after we embarked on our joint project, geopolitics around the deep-sea mining landscape began to shift dramatically. In February 2025, China signed an agreement with the Cook Islands government to collaborate on deep-sea mining research and exploration. At the same time, it was pursuing a similar deal with the archipelago nation of Kiribati, marking a notable expansion of Chinese influence in the Pacific. China holds the largest number of exploration contracts issued by the International Seabed Authority (ISA), the U.N.-affiliated deep-sea mining regulator, and is also its biggest financial contributor. It also operates the world’s largest oceanographic research fleet. Against this backdrop, we kept returning to a central question: was China’s pursuit of deep-sea mining driven solely for accessing mineral resources, or was it also shaped by broader geopolitical strategy? Through extensive reporting, we learned that China’s interest in seabed mining was motivated by both of these things, and that some of its vessels were engaged in both deep-sea mining work and militarily strategic surveillance. Meanwhile, deep-sea mining efforts have been gathering pace in the United States. In March 2025, The Metals Company,…This article was originally published on Mongabay

This is part 1 of a two-part series examining the U.S.’s efforts to begin deep-sea mining in federal waters. Part 1 explores the process behind proposed lease sales in U.S. federal waters and reactions to those plans. Part 2, to be published soon, will examine the regulations that would govern the industry. The U.S. agency responsible for overseeing deep-sea mining in federal waters is preparing to auction off seabed blocks within months — a step that could kick-start commercial-scale deep-sea mining and make the U.S. one of the first countries to allow it. Deep-sea mining has not yet begun anywhere in the world. Opponents say it could cause widespread and irreversible damage to the marine environment if it begins, while supporters say it could provide an important source of critical minerals. In a budgetary document released in April 2026, the U.S. Department of the Interior (DOI) indicated it intends to hold at least three offshore lease sales during the 2026 and 2027 fiscal years. The lease sales will take place through competitive auctions, providing a pathway for winning companies to gain exclusive rights to explore and exploit minerals in designated tracts of seabed. The first sale is slated for the federal waters of American Samoa in August 2026; a second in the Commonwealth of the Northern Mariana Islands (CNMI) in November 2026; and a third in Alaska in 2027. A spokesperson for the Bureau of Ocean Energy Management (BOEM), the U.S. agency currently responsible for the development of offshore energy…This article was originally published on Mongabay
